NAME

SYNOPSYS

The quadrature class defines a container for a quadrature formulae on
the reference element (see . reference_element internal}'). This
container stores the nodes coordinates and the weights.

THECONSTRUCTORTAKESTWOARGUMENTS

the reference element K and the order r of the quadrature formulae.
The formulae is exact when computing the integral of a polynom p that
degree is less or equal to order r.

LIMITATIONS

The formulae is optimal when it uses a minimal number of nodes n.
Optimal quadrature formula are hard-coded in this class. Not all
reference elements and orders are yet implemented. This class will be
completed in the future.
